Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610026, here are decompositions:

3 + 31610023 = 31610026
17 + 31610009 = 31610026
53 + 31609973 = 31610026
59 + 31609967 = 31610026
89 + 31609937 = 31610026
179 + 31609847 = 31610026
233 + 31609793 = 31610026
257 + 31609769 = 31610026

Showing the first eight; more decompositions exist.
